Then, the composition of linking part 5230 is illustrated.Linking part 5230 has nut guide card (Nut Guide, spigot nut) 5232nd, a pair of of Y-axis track 5234, a pair of of Z axis track 5235, intermediate microscope carrier 5231, a pair of of X-axis track 5237, a pair of of X-axis rotor Block 5233 and rotor block installation component 5238.
Nut guide card 5232 is fixed on ball nut 5219.In addition, a pair of of Y-axis track 5234 is to be stretched together to Y direction The track gone out, and vertical direction is fixed in the end of the X-axis positive direction side in nut guide card 5232 side by side.In addition, a pair of of Z axis rail Road 5235 is the track stretched out together to Z-direction, and Y-axis is fixed in the end of the X-axis negative direction side in platform 5100 side by side Direction.Intermediate microscope carrier 5231 is that the Y-axis rotor block 5231a of each combination with the Y-axis track 5234 is arranged on X-axis negative direction side Face, the Z axis rotor block 5231b of each combination with Z axis track 5235 is arranged on to the square in the face of X-axis positive direction side, and to Y Both axis track 5234 and Z axis track 5235 are slideably formed.
That is, intermediate microscope carrier 5231 can be slided compared with platform 5100 in Z-direction, and compared with 5232 energy of nut guide card It is enough to be slided in Y direction.Therefore, intermediate microscope carrier 5231 can be slided compared with platform 5100 in Y direction and Z-direction.Cause And even if platform 5100 is shaken to be added in Y direction and/or Z-direction, nut by other actuators 5300 and/or 5400 Guide card 5232 still will not therefore displacement displacement.That is, generated because platform 5100 is conjugated in the displacement of Y direction and/or Z-direction Bending stress will not be applied to ball screw 5218 or bearing portion 5216, coupler 5260 etc..
A pair of of X-axis track 5237 is the track stretched out together to X-direction, and on the bottom plate 5242 of supporting device 5240 It is fixed on Y direction side by side.Each combination of X-axis rotor block 5233 and the X-axis track 5237, can be along X-axis track 5237 And it slides.Rotor block installation component 5238 is to be fixed on 5232 bottom of nut guide card in a manner of being stretched out towards Y direction both sides The component in face, and X-axis rotor block 5233 is fixed on the bottom of rotor block installation component 5238.In this way, nut guide card 5232 via Rotor block installation component 5238 and X-axis rotor block 5233 and be directed at X-axis track 5237, thereby, it is possible to only X-direction move It is dynamic.
In this way, because the moving direction of nut guide card 5232 is only limited in X-direction, servo motor unit is driven 150X and when rotating ball screw 5218, nut guide card 5232 and the platform 5100 that is combined with the nut guide card 5232 are in X-axis It retreats in direction.
(it is proximal lateral in Figure 34, is right in Figure 35 in a side side of the Y direction side of rotor block installation component 5238 Side) 5238a is configured with position detection component 5250.Position detection component 5250 has at certain intervals (arrangement) side by side in X-axis 3 proximity sensors 5251 in direction, the detection arranged on the side 5238a of rotor block installation component 5238 with plate 5252 and are propped up Hold the retaining plate of sensor 5253 of proximity sensor 5251.Proximity sensor 5251 is can detect before each proximity sensor Whether object component close to (such as 1 millimeter within) is had.Because the side 5238a of rotor block installation component 5238 is with connecing Nearly sensor 5251 is sufficient away from so whether proximity sensor 5251 can detect has inspection before each proximity sensor 5251 It surveys with plate 5252.The control unit C5 of vibration-testing apparatus 5000 for example can be anti-using the testing result of proximity sensor 5251 Feedback control servo motor unit 150X (Figure 38).
In addition, on the bottom plate 5242 of supporting device 5240, X-axis rotor block is configured equipped with being clipped from X-direction both sides 5233 confinement block 5236.The confinement block 5236 is used to limit the moving range of nut guide card 5232.That is, servo motor list is driven First 150X and make nut guide card 5232 to X-axis positive direction continue to move to when, be finally configured at the confinement block 5236 of X-axis positive direction side It is contacted with rotor block installation component 5238, nut guide card 5232 can not excessively be moved in X-axis positive direction.Make 5232 court of nut guide card Also same when being continued to move to X-axis negative direction, the confinement block 5236 and rotor block installation component 5238 for being configured at X-axis negative direction side connect It touches, nut guide card 5232 can not excessively be moved in X-axis negative direction.
Except the direction of setting is different, (X-axis is mutual with Y-axis from the second actuator 5300 for first actuator 5200 described above Change) outside, construction is identical.It omits and is described in detail accordingly, with respect to the second actuator 5300.
Then, the composition of the 3rd actuator 5400 of embodiment of the present invention is illustrated.Figure 36 is (from Figure 16 from X-direction Lower section upward) viewing 5100 and the 3rd actuator 5400 of platform side view.The side view in order to show internal structure and A shortcoming part.In addition, Figure 37 is the platform from Y direction (from left side of Figure 33 to the right) viewing embodiment of the present invention 5100 and the 3rd actuator 5400 side view.Figure 37 is short of a part to show internal structure.In addition, it is said in following That will be defined as Y-axis positive direction along from the direction of the second actuator 5300 towards Y-axis of platform 5100 in bright, will along from The direction of platform 5100 towards the Y-axis of the second actuator 5300 is defined as Y-axis negative direction.
As shown in Figure 36 and Figure 37, be equipped on substrate 5402 stretched out by vertical direction multiple beam 5422a, with from top The frame 5422 that the top plate 5422b for covering the plurality of beam 5422a and configuring is formed.The lower end of each beam 5422a is welded in substrate 5402 the upper surface of, upper end is welded in below top plate 5422b.In addition, the bearing support plate 5442 of supporting device 5440 passes through nothing The bolt of diagram and be fixed on the top plate 5422b of frame 5422.The bearing support plate 5442 is for supporting platform 5100 (Figure 33) vertical direction add the driving mechanism shaken 5410 and for by driving mechanism 5410 plus shake movement be transferred to it is flat The component of the link mechanism 5430 of platform.
Driving mechanism 5410 has servo motor unit 150Z, coupler 5460, bearing portion 5416,5418 and of ball screw Ball nut 5419.Coupler 5460 links the drive shaft 152Z of servo motor unit 150Z and ball screw 5418.In addition, axis Bearing portion 5416 is fixed on the bearing support plate 5442, rotatably supports ball screw 5418.Ball nut 5419 does not exist It moves around its axis and is supported by bearing support plate 5442, and combined with ball screw 5418.Thus, drive servo motor During unit 150Z, ball screw rotates, and ball nut 5419 is retreated in its direction of principal axis (i.e. Z-direction).Pass through the ball nut 5419 movement is transferred to platform 5100 via link mechanism 5430, and platform 5100 is driven in Z-direction.Then, by with The short cycle switches the rotation direction of servo motor unit 150Z to control servo motor unit 150Z, can be with desirable amplitude It by platform 5100 plus shakes with the cycle in Z-direction (vertical direction).
Below the bearing support plate 5442 of supporting device 5440, it is fixed with via 2 link plates 5443 towards level The widened rotor bearing cock 5446 in direction (X/Y plane).Below rotor bearing cock 5446 hang servo motor unit 150Z and It is fixed.Opening portion 446a is equipped in rotor bearing cock 5446, the drive shaft 152Z perforations of servo motor unit 150Z should Opening portion 446a, side links with ball screw 5418 above rotor bearing cock 5446.
In addition, in the present embodiment, because the direction of principal axis (vertical direction, Z-direction) of servo motor unit 150Z The height of size ratio frame 5422 is big, so the major part of servo motor unit 150Z is configured at the position lower than substrate 5402. Thus, it is equipped with to store the blank part 5002a of servo motor unit 150Z in device pedestal 5002.In addition, in substrate In 5402 be equipped with servo motor unit 150Z by using opening 5402a.
Bearing portion 5416 penetrates through bearing support plate 5442 and sets.Further, since the construction of bearing portion 5416 and first causes Bearing portion 5216 (Figure 34, Figure 35) in dynamic device 5200 equally, therefore omits detailed description.
Then, the composition of linking part 5430 is illustrated.Linking part 5430 have movable frame 5432, a pair of of X-axis track 5434, A pair of of Y-axis track 5435, multiple intermediate 5431, two pairs of Z axis tracks 5437 of microscope carrier and two pairs of Z axis rotor blocks 5433.
Movable frame 5432 has the frame portion 5432a for being fixed on ball nut 5419, the upper end for being fixed on frame portion 5432a Top plate 5432b and two edge of X-direction from top plate 5432b stretch out and fixed side wall 5432c downwards.A pair of of Y-axis track 5435 be together to Y direction stretch out track, and above the top plate 5432b of movable frame 5432 (arrangement) arranged side by side in X Direction of principal axis and fix.In addition, a pair of of X-axis track 5434 is the track stretched out together to X-direction, and below platform 5100 It (arranges) and is fixed in Y direction side by side.Intermediate microscope carrier 5431 is the X-axis rotor block 5431a will to be combined with X-axis track 5434 Arranged on top, and by the Y-axis rotor block 5431b of each combination with Y-axis track 5435 arranged on the square of lower part, and form energy It is enough to be slided compared with both X-axis track 5434 and Y-axis track 5435.In addition, intermediate microscope carrier 5431 is in X-axis track 5434 and Y The each position that axis track 5435 intersects respectively sets one.Since X-axis track 5434 and Y-axis track 5435 respectively set two respectively, X Axis track 5434 intersects with Y-axis track 5435 at 4.Therefore, microscope carrier 5431 among 4 is used in present embodiment.
In this way, each intermediate microscope carrier 5431 can be slided compared with platform 5100 in X-direction, and compared with movable frame 5432 can slide in Y direction.That is, movable frame 5432 can be slided compared with platform 5100 in X-direction and Y direction.Cause And even if platform 5100 is shaken by other actuators 5200 and/or 5300 to be added in X-direction and/or Y direction, activity Frame 5432 still will not therefore displacement displacement.That is, because platform 5100 is produced when the displacement of X-direction and/or Y direction conjugates Raw bending stress will not be applied to ball screw 5418 or bearing portion 5416, coupler 5460 etc..
In addition, in present embodiment, because the taking the weight of bigger platform 5100 and workpiece on movable frame 5432, So the interval that X-axis track 5434 and Y-axis track 5435 are taken is than the Y-axis track 5234 of the first actuator 5200 and Z axis track 5235 is wide.Thus, in the same manner as the first actuator 5200, it is set to only link platform 5100 and activity box by microscope carrier among one During the composition of frame 5432, intermediate microscope carrier will maximize, and cause the load increase for being applied to movable frame 5432.Thus, this implementation In mode, it is set to configure small-sized intermediate microscope carrier 5431 in each X-axis track 5434 and each several part that Y-axis track 5435 intersects Composition, will be applied to movable frame 5432 magnitude of load inhibit in necessary bottom line.
